'Seventh' in the Bible

So all the men of Israel were assembled in the presence of King Solomon in the seventh month, the month of Ethanim, at the festival.

In the twenty-seventh year of Judah’s King Asa, Zimri went in, struck Elah down, killing him. Then Zimri became king in his place.

In the twenty-seventh year of Judah’s King Asa, Zimri became king for seven days in Tirzah. Now the troops were encamped against Gibbethon of the Philistines.

On the seventh time, he reported, “There’s a cloud as small as a man’s hand coming from the sea.”Then Elijah said, “Go and tell Ahab, ‘Get your chariot ready and go down so the rain doesn’t stop you.’”

They camped opposite each other for seven days. On the seventh day, the battle took place, and the Israelites struck down the Arameans—100,000 foot soldiers in one day.
